This directory lists 46 broaching companies across the United States, from specialized job shops excelling in complex prototype keyseating to large production houses offering high-volume spline broaching and surface broaching services.
Buyers frequently encounter challenges in achieving specific internal forms, intricate external profiles, or precise gear teeth that demand high repeatability and surface finish. They're often solving for faster cycle times for features like hexes, squares, or specific tooth geometries, or overcoming limitations of milling or EDM when dealing with hardened materials or tight tolerance requirements for spline shafts.
Broaching suppliers vary significantly. Some focus on internal broaching like keyseating or internal splines, often requiring custom pull broaches or push broaches. Others specialize in surface broaching for external forms, utilizing vertical or horizontal machines, sometimes with automated part loading for high volumes. There are also niche providers focusing on rotary broaching for smaller, often blind hole features, or those with extensive in-house broach tooling design and manufacturing capabilities.
To engage effectively, buyers should prepare detailed CAD models, material specifications, required tolerances (especially for form, position, and surface finish), and anticipated annual volumes. Suppliers, in turn, will want to understand the application, any critical features, and existing quality requirements to determine the optimal broaching method and tooling strategy, which heavily influences lead time and cost.
A noticeable trend in the broaching sector is the increasing integration of advanced robotics for automated part loading and unloading, especially in high-volume production environments using continuous surface broaching or pot broaching machines. This, coupled with greater adoption of advanced metrology for in-process inspection of broached features, is driving higher throughput and improved quality consistency, particularly for critical aerospace and automotive components.

Pull broaching involves a broach tool being pulled through or over a workpiece, common for internal features like splines or keyways, and generally produces a better surface finish and longer tool life due to better chip evacuation. Push broaching uses a shorter, more robust tool pushed through the workpiece, often preferred for shorter features, blind holes, or when the workpiece cannot withstand significant tensile stress. The choice often depends on the part geometry, material, and required finish.
Broach tooling is a highly specialized, precision-engineered component and often represents a substantial upfront investment, typically 30-70% of the initial project cost, especially for custom profiles like involute splines or complex internal forms. Lead times for new tooling can range from 8 to 20 weeks or more, depending on complexity and the broach manufacturer's backlog. It's critical to factor this into your budget and project timeline early on.
While broaching is most efficient and produces the best tool life with materials in an annealed or pre-hardened state (typically up to 30-35 HRC), specialized broaches and processes can handle certain hardened materials. However, broaching very hard materials (e.g., 45 HRC+) significantly reduces tool life, increases cycle time, and may lead to microfractures or accelerated tool wear. For such applications, alternative methods like grinding or EDM are often more suitable or post-broaching heat treatment is common.
To get an accurate quote, you must provide a detailed 2D print (with all tolerances, especially geometric tolerances like concentricity or parallelism for broached features) and a 3D CAD model. Specify the material type and hardness, annual volume requirements, and any critical surface finish callouts. Also, clearly state any secondary operations (like deburring, heat treatment, or plating) if the broacher is expected to manage them.
Maintaining tight tolerances in spline broaching or keyseating often battles issues like tool wear affecting feature size, material spring-back, or machine deflection. Experienced suppliers counter this with rigorous tool maintenance schedules, using high-quality carbide or HSS tool materials, precise machine calibration, and implementing in-process or post-process inspection using go/no-go gauges, splinometers, or CMMs. They'll also account for material characteristics and optimize chip load to minimize stress and distortion.
